Is it necessary to go to the 4s shop to clean the accelerator?

When the automobile accelerator needs to be cleaned in a 4s shop, the cleaning method is as follows: 1. First, pull up the hood handle, open the hood and support it with a bracket. Then, pull the automatic throttle position away from the air cleaner tube and pull the throttle with a tool. 2. Clean the carbon deposit in the throttle valve with Huayou cleaning machine, dry it after cleaning and reinstall it. 3. Now, we will introduce the simplest method, that is, remove the separation filter element pipeline. Start the car, spray Huayou cleaning machine on the accelerator, and step on the accelerator to refuel. At this point, you can see that Huayou bath will flow out. In order to prevent the Chinese oil bath from flowing out of the line, you can put a towel under it. 4. After cleaning, reinstall the filter tube.
